yes ... was very tricky.any change whatsoever ... in density or placement ...and the whole thing is different.question ...is there a random function we can use?and if so ... a seed on can replicate to start thepseudo randomization?thanks-----------------Random numbers are far too important to be left to chance.

I have not study box2d ( http://box2d.org ) very deeply now. So I don't know how the random factor affect the whole simulation.

The other factor is the simulation time step. Now the time step is the real time interval, it is not fixed, which means it also has some randomness. Maybe I will add the fixed time step feature later.-----------------My games: Tapir GamesMy phyards: Tapir@phyard

yes, i noticed the time step can change the interaction.i was surprised that the above puzzle reproduced exactly ...that is GOOD! now we can have a scientific experiment. ;)

ideally, it is great to have the simulation reproduce exactly depending on the starting seed so one can retain some controland repeatability ...but still introduce 'pseudo randomness' ...because then you can end up with very interesting results ...but are able to reproduce them because you are startingwith a 'seed' for the 'randomization.'so if you like what you see ...you can repeat it.

great forum ...this is exactly what i was looking for ...trying to find more stuff like 'Day of the Bobteds'do you know it?http://foon.co.uk/farcade/bobteds/this is what got me interested in flash programming ...[which i still know nothing about!]the physics one could simulate.his 'netshift' is pretty cool too.http://foon.co.uk/farcade/netshift/

fun stuffthanks for this site.and it's just beginning ...who knows what we will discover? ;)-----------------Random numbers are far too important to be left to chance.
